Product Description

12-sided dodecahedral die labeled {1, 2, 3, 5, 7, 11, 15, 22, 30, 42, 56, 77} which are the number of ways to partition 1, 2, 3, 4, ... 12 identical objects. This D12 can be used as an alternative to a doubling cube or Fibonacci-ing cube in backgammon and other games since the numbers do not grow too quickly.

Partition numbers are interesting because there is no simple closed formula for P(n), the number of ways to partion n objects. P(n) grows faster than any power function c*n^k but slower than any exponential function c*k^n.
